碩士 === 國立成功大學 === 光電科學與工程學系 === 103 === In this thesis, two referred ways to be used for 3D imaging performance in integral imaging system is demonstrated and experimentally compared with human visual sensation including human vision considerations and image pickup via computer graphics. Experiment results show that the number of lens units is an important factor to affect 3D imaging performance in integral imaging systems. The more lens units in lens arrays are, the sharper imaging performance shown in the edge of the images are. The optical wavelength is also factor to affect imaging performance in integral imaging systems. The shorter wavelength is, the clearer images are. When viewing 3D images at an optimal distance, the lens arrays with shorter focal lengths show worse imaging quality than that in lens arrays with larger focal lengths due to optical diffraction effect. For one-dimensional integral imaging system, the larger evaluated PSNR values show consistence with human vision sensation when comparing imaging performance via an additional computer graphic pickup. Simultaneously, using higher resolution parallax images largely reduce the degree of color separation occurred in rendered images.
